HERBERT G. THOMSON, OF NEW YORK, N. Y.

GATE.

Specification of Letters Patent.

Patented Uct. 29, 1918.

Application filed June 14, 1918. Serial No. 239,973.

To all whom it may concern:

Be. it known that I, HERBERT G. THOM- SON, a citizen of the United States, and resident of the city of New York, borough of Manhattan, in the county of New York and State of New York, have invented certain newand useful Improvements in Gates, of which the following is a specification.

This invention relates to that class of gates in which heavy wire fabric is supported under tension by and within a rectangular frame structure of metal work.

The object of my invention is the provision ofa gate wherein the membersof the frame structure are united and reinforced in such a manner as to provide a substantially integral construction possessing great strength, rigidity and relative lightness.

A further object of my invention is the provision of a simple and reliable hinge connection for a gate of the character mentioned.

A further object of my invention is the provision of novel means whereby wire fabric can be readily applied to the frame structure and supportedtherein under tens1on. r 1

With these and other objects in view my invention comprises, in agate, various novel features of construction and combinations of parts which will behereinafter described and claimed.

In the.drawings Figure 1 is a partial front elevation of the lower portion of a swinging gate embodying my invention.

Fig. 2 is a transverse horizontal section, enlarged, as on the line 2.-2 of Fig. 1.

Fig. 3 is a horizontal section, as on the line 33 of Fig. 1.

Fig. 4 is a perspective View of a corner of the gate frame and the adjacent supporting post and hinge connections, show ing the complementary hinge elements separated from each other.

Fig. 5 is adetached perspective view of one of the hinge elements and a portion of the adjacent rail of the gate frame.

Fig. 6 is an elevation of'the lower middle portion of a sliding gate embodying my invention, showing one of the guide rollers and its supporting parts.

Fig. 7 is a transverse vertical section, onlarged, as on the line 7-7 of Fig. 6, the Wire fabric being omitted.

Referring to the drawings, 10 designates a portion of the lower horizontal rail of a gate frame, and 11 portions of the vertical end members thereof, it being understood .that the top and bottom rails are or may be of the same construction, and that the vertical members at the respective ends of the frame also are or may be similar in construction to each other.

12 designates interlooped or interwoven open wire fabric which is secured to and held under tension between the respective end members of the frame, as hereinafter described.

In a preferred form of embodiment of my invention, each rail 10 comprises a stout metal tube, and each end member 11 comprises two channel bars arranged back to back and in spaced relation to each other and connected at intervals by means of transverse bolts 11 At or near each end of the respective pairs of bars are two exteriorly arranged parallel cheek members 13 which extend horizontally toward and embrace the adjacent rail. These members 13 are composed of sections of channel iron whereof the channels are arranged to face each other and to receive the adjacent portions of the cylindrical surface of the rail. The web and flanges of each cheek member are so proportioned as to contact with the confined portion of the rail at three circumferentially spaced points, indicated at m Fig. 2,that is, the vertical inner face of the web contacts tangentially with the opposing circumferential surface of the rail and the inner edges of the flanges contact wlth the two portions of such circumferential surface'opposed thereto.

' In view of the factthatthe outer surface of the rail is a true circle and that the inner surfaces of the webs are straight lines, the contact of each surface of a web is necessarily at a single point. This point, in addition to the points of contact of the flange edges with the rail, resultsin three points of contact for each cheek member. It is thought that this is apparent from Figs. 2 and 7 and hence the proximate portion of the rail is firmly gripped and sustained against lateral and vertical displacement.

The flanges 14 of each cheek member 13 are electrically welded to the contiguous flanges 15 of the adjacent bar 11, and. hence said bar and cheek member constitute, in effect, an integral structure. The comp1ementary cheek members and'the portion of the rail embraced thereby have alimng transverse holes therein for the passageof scour ing bolts 16, 16. Nuts 17 applied to the projecting threaded ends of the bolts coact structure. The lower hinge connection only is illustrated .as the upper connection is or may be a duplicate thereof. When a hinge connection is employed the outer ends of the adjacent cheek members 13 are extended somewhat beyond the bars, as at 18. An element of the hinge connection includes a block 19 having a tongue-like extension 20, said block being formed and proportioned to fit snugly between the spaced lower portions of the channeled ends 18 of the cheek members, and said tongue extension being shaped to fit snugly between the vertical frame bars 11 and enter the adjacent open end of the rail 10. The inner end of the tongue is transversely perforated for the passage of the bolt 16, and the ends 18 and block are similarly perforated for the passage of a securing bolt 21. The block 19 is provided with an outwardly extending perforated portion 22 which is connected by means of a vertical pintle 23 to a complementary hinge member 24 projecting from a clamp bracket 25 on an adjacent post 26. By this construction the hinge connection is-rigidly attached tothe rail and end bars of the gate frame and at the same time serves as an effective space member for said bars.

As illustrated in Figs. 1 and 3, the spaced bars 11 at the respective ends of the gate frame facilitate the application of the woven fabric to the frame and the use therewith of simple and efficient devices whereby said fabric is held under tension; that is to say, the ends of the fabric are entered in the spaces between the respective pairs of vertical bars; a vertical rod 27 is passed through the loops of the fabric at one end of the gate so as to bear against the adjacent cross bolts 11 threaded hook-bolts 28 are engaged at intervals with the loops at the other endof the fabric, and bridge-pieces 29 are interposed betweenthe spaced bars and the nuts 30 of the: respective bolt hooks. Hence by manipulating the nuts the hooks may be ad usted todraw the fabric taut and-maintain it under uniform tension. V

In Figs. 6 and 7 is illustrated agate con struction wherein two panels including a pair of central vertical bars llare employed.

In this construction the cheek members 13 are eloTigated so as to extend some distance beyond each side'of'the bars and overlap the lower alining rails 10 of the respective panels. These members are electrically welded to the adjacent bars and are secured by bolts 16 to the contiguous rails 10 ofthe panels; the whole constituting a strong and rigid structure.

The plural panel construction just. described is especially, though not necessarily, designed for, a sliding gate having horizon tal guide railsat the top andybotto'm thereof adapted to bear on suitably-ehsposedsheaves or rollers. A portion of; the lower guide rail, which is indicated at 31, is conveniently bolted to the extended cheelc'm'embers, and also to the outer end cheek members of the two panels, said outer members being of the general character first described. One of the guide sheaves or rollersfor thelower guide rail is indicated at 32; the same being mounted in aclamp bracket-33 at thefoot ofa supporting post 34. i i I Various changes in the form and construction ofthe parts above-described may be made without departingfrorn the principle of the invention as defined in the appended claims.
